PIR / PUR Insulated Sandwich Panels

PIR / PUR
Insulated Metal Panels

PIR is our preferred option, with PUR available for suitable conditions. Compare both materials for industrial roof, wall and cold-chain applications.

System Position

PIR Preferred. PUR Where Appropriate.

Compare PIR and PUR together. BESRIN generally recommends PIR for balanced fire, thermal and long-term stability performance, while PUR remains an option where temperature, compliance and cost requirements are defined. Final performance depends on formulation, density, facings, profiles, joints, details and relevant test evidence.

PIR vs PUR

Two Materials. A Clear Comparison.

Compare PIR and PUR core options here. Performance must be confirmed against the selected specification and its test reports.

PIR / RECOMMENDED

PIR: Preferred Option

Typically offers balanced fire behavior, temperature range and dimensional stability for industrial and cold-chain projects demanding long-term performance.

View Details
PUR / OPTIONAL

PUR: Application-Specific Option

Efficient insulation and economy for conventional chilled and frozen storage with defined temperature and compliance requirements.

View Details
THERMAL

Thermal Performance

Both are efficient insulating cores. Assess thickness, joints, thermal bridges and aging alongside conductivity.

Cold Chain Application

PIR/PUR High-Performance Envelope Applications

Select PIR or PUR for cold-chain applications here. PIR is preferred for demanding fire, thermal and stability requirements; PUR is available for clearly defined temperature, compliance and cost conditions.

Equipment & Process

Continuous Production & Manufacturing Process

Facing treatment, roll forming, foam metering, double-belt curing, cutting and packing form a continuous process. Equipment and settings are confirmed for each specification.

PUMA continuous composite line overview
CONTINUOUS LINE

Continuous Composite Production

Core density, closed-cell content, thermal uniformity and flatness depend on coordinated metering, double-belt temperatures, line speed and curing time. Siemens PLC monitoring and records support batch consistency.
